A few remaining ints changed to OffsetT. This allows us to switch cub to use 64 bit offsets via cub::DispatchScan without crashing.

Related: dmlc/xgboost#6234

Nice, thanks for tracking those down. I have one of these fixes in #210, but we definitely still need the others. You may be interested in some of the other DeviceScan fixes from that PR, too.

Also be aware of #212. At some point I'd like to fix this in DeviceScan directly so you won't have to jump through hoops to deal with the Dispatch layer.

Any updates on getting this or #210 merged? We are still blocked on this in xgboost.

Our internal CI/integration workflow is currently broken due to issues beyond our control. Hoping it's resolved by next week.

Once we have access to our CI again I'll run this (and the other ~15 Thrust/CUB PRs currently blocked on CI) through testing ASAP and hopefully land them in time for the 1.11.0 release scheduled for 2020-11-15.
